Ações bioquímicas/fisiológicas

FX1 is a BCL6 inhibitor that effectively blocks BCL6 N-terminal BTB domain-mediated corepressors chromosome recruitment (by 61-87%/SMRT and 67-82%/BCOR; 50 μM FX1 for 30 min) and selectively suppresses BCL6-depenent growth (GI50 16-54 μM; >125 μM against BCL6-independent cells) in diffuse large B cell lymphoma (DLBCL) cultures, exhibiting greater affinity than its structure analog 79-6 or BCL6 corepressor SMRT for BTB domain (KD = 7 μM/FX1, 30 μM/SMRT, 129 μM/79-6). FX1 shows greater efficacy than 79-6 in reversing BCL6/corepressors-mediated target genes repression in vitro (IC50 = 35 μM vs. 318 μM with 79-6 by HEK293T-based reporter assay) and in suppressing OCI-Ly7 DLBCL xenograft tumor growth mice in vivo (100% vs. 45% suppression with respective compound via 25 mg/kg/day i.p.).
Second generation 79-6 derived BCL6 inhibitor with improved efficacy against diffuse large B cell lymphoma (DLBCL) both in vitro and in vivo.

Diffuse large B cell lymphomas (DLBCLs) arise from proliferating B cells transiting different stages of the germinal center reaction. In activated B cell DLBCLs (ABC-DLBCLs), a class of DLBCLs that respond poorly to current therapies, chromosomal translocations and amplification lead

Inhibition of the protein-protein interaction between B-cell lymphoma 6 (BCL6) and corepressors has been implicated as a therapeutic target in diffuse large B-cell lymphoma (DLBCL) cancers and profiling of potent and selective BCL6 inhibitors are critical to test this hypothesis.

B-cell CLL/lymphoma 6 (BCL6) exerts oncogenic effects in several human hematopoietic malignancies including chronic myeloid leukemia (CML), where BCL6 expression was shown to be essential for CML stem cell survival and self-renewal during imatinib mesylate (IM) treatment. As several lines

The EZH2 histone methyltransferase mediates the humoral immune response and drives lymphomagenesis through formation of bivalent chromatin domains at critical germinal center (GC) B cell promoters. Herein we show that the actions of EZH2 in driving GC formation and lymphoma
